I have a project I'm working on which consists of a stand-alone network that uses a network simulation protocol which uses broadcast IP to send data to all nodes in the network. Pretty straight forward. But, now I'm using WANem (a Linux LiveCD which acts as a WAN Emulator) which allows you to emulate a WAN by dialing a variety of parameters (latency, bandwidth limits, etc). The problem is that for the WANem software to all packets must first be routed to the WANem machine, which applies the WAN effects and then sends the packets on its way. This is accomplished by adding the WANem IP address to the routing tables for each computer in the network. The problem is that the network simulation software I'm using will only send data out via Broadcast IP, and thus, ignores the route I've added to tell the packets to first go to the WANem machine. I'm using a Linksys WRT54G and wanted to know if any of the available 3rd party firmware packages would allow virtual subnetting. Or, since networking and routing is certainly not my strong suite, if there is some other approach that would work. If one router won't do it alone, is there a way to use two routers to accomplish this? Any help would be greatly appreciated.
